Description

Technical Field

[0001] The present application relates to the field of photovoltaic technology, and in particular to a suspension cable fixing device, a flexible photovoltaic bracket and a photovoltaic system. Background Art

[0002] Flexible photovoltaic brackets are a method of replacing rigid purlins with suspension cables to form a flexible cable structure, so that photovoltaic modules can be directly installed on the suspension cables. This design can avoid unfavorable geographical factors such as undulating mountains and high vegetation, and broaden the installation range of photovoltaic systems. At the same time, the installation cost of flexible photovoltaic brackets is lower than that of rigid brackets.

[0003] In the related technology, the flexible photovoltaic bracket is completely supported by the suspension cable to bear the gravity of the photovoltaic module, and the weight of the suspension cable, wind pressure, snow pressure and other factors affect the whole system, so it is necessary to have a higher array plane deflection and wind resistance. Generally, the problem is solved by applying a greater prestress to the suspension cable. At this time, how to stably and fixedly connect the photovoltaic module with the suspension cable after the prestress is applied becomes an urgent problem to be solved.

[0004] At present, the connection between photovoltaic modules and suspension cables is mainly to use a suspension cable fastening mechanism composed of a U-shaped lock and a connecting plate to fix the two photovoltaic modules to the suspension cables. However, the installation of this suspension cable fastening mechanism is relatively complicated, and it is not convenient to adjust the position of the photovoltaic modules and the connecting plate after they are fixed. Utility Model Content

[0019] The tail portion of the buckle plug is provided with a limiting portion which can cooperate with the corresponding stop portion to limit the forward movement of the buckle plug along the insertion direction.

[0020] In one embodiment, the stop portion is configured as a stop groove formed at the plug-in end of the first locking tongue piece;

[0021] The two limiting portions are configured as locking edges protruding outward in opposite directions.

[0022] In one of the embodiments, the snap-in plug structure has a groove extending from the tail portion to the insertion head portion, so that the snap-in plug structure forms two elastic second locking tongue pieces.

[0023] In one embodiment, the locking assembly includes a locking member penetrating the first locking tongue piece and the buckle plug, and an adjusting member detachably connected to the locking member;

[0024] The adjusting member is configured to be able to be maintained at different positions along the longitudinal extension direction of the locking member, so that the two first locking tongue pieces can move toward each other or away from each other.

[0025] In one embodiment, the adjusting member is threadedly connected to the locking member.

[0031] The above-mentioned flexible photovoltaic support; and

[0032] A photovoltaic component comprises a frame, wherein the buckle sleeve is connected to the bottom side of the frame through the locking assembly.

[0033] In the technical solution of the present application, when the cable fixing device is used, on the one hand, the buckle sleeve can be fixed to the bottom side of the photovoltaic component by the locking assembly, and on the other hand, the buckle plug can be inserted into the plug accommodating cavity through the insertion port, and then the locking assembly is used to make the two first locking tongues of the buckle sleeve move toward each other, so that the buckle sleeve is switched from an unlocked state to a locked state, and then the buckle plug can be moved forward along the insertion direction, thereby forming a fixed position that presses the cable against the cable fixing cavity. In this way, the photovoltaic component can be fixed on the cable by the cable fixing device, and compared with the traditional cable fastening mechanism, the cable fixing device of the present application is used to install a corresponding photovoltaic component on the cable, so that the cable fixing device can be independently adjusted according to the installation position of the photovoltaic component, which increases the installation flexibility and convenience of the cable fixing device, simplifies the installation process of the photovoltaic component, and facilitates the position adjustment of the photovoltaic component.

[0047] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0048] In the description of the present application, it should be understood that if the terms "upper", "lower", "front", "back", "top", "bottom", "inside", "outside", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0049] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0050] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0051] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0052] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0053] The traditional cable fastening mechanism includes a U-shaped lock and a connecting plate, and is used to connect two adjacent photovoltaic modules. During the installation process, multiple photovoltaic modules usually need to be fixed on the cable, which results in the installation of the traditional cable fastening mechanism needing to take into account multiple photovoltaic modules, which in turn results in the installation of the traditional cable fastening mechanism being relatively complicated and extremely inconvenient, and it is not easy to adjust the position of the photovoltaic module after it is fixed to the connecting plate.

[0054] In order to solve the problem that the traditional cable fastening mechanism is complicated to install and it is inconvenient to adjust the position of the photovoltaic module after it is fixed to the connecting plate, the present application designs a cable fixing device, a flexible photovoltaic bracket and a photovoltaic system, which can be used to install a photovoltaic module on the cable accordingly, so that the cable fixing device can be independently adjusted according to the installation position of the photovoltaic module, thereby increasing the installation flexibility and convenience of the cable fixing device, simplifying the installation process of the photovoltaic module, and facilitating the position adjustment of the photovoltaic module.

[0055] Figure 1 The schematic diagram shows the structure of fixing the photovoltaic assembly 30 on the suspension cable 20 by using the suspension cable fixing device 10 in one embodiment of the present application. Figure 2 A schematic structural diagram of a suspension cable fixing device 10 in an embodiment of the present application is shown.

[0056] See also Figure 1 and Figure 2 A suspension cable fixing device 10 provided in one embodiment of the present application includes a buckle sleeve 110 , a buckle plug 120 and a locking assembly 130 .

[0057] The snap sleeve 110 has a suspension cable fixing cavity A and a plug accommodating cavity B which are connected to each other. The snap sleeve 110 is also provided with an insertion port C which is connected to the plug accommodating cavity B at its plug-in end, so that the snap sleeve 110 is constructed to form two elastic first locking tongue pieces 111, and the snap plug 120 is configured to be able to be inserted into the plug accommodating cavity B through the insertion port C.

[0058] The locking assembly 130 is releasably disposed on the two first locking tongue pieces 111 , so that the two first locking tongue pieces 111 can move toward or away from each other, thereby switching the buckle sleeve 110 between a locked state and an unlocked state.

[0059] It can be understood that the snap plug 120 can be inserted into the plug accommodating cavity B through the insertion port C, and the two first locking tongue pieces 111 can be moved toward each other through the locking assembly 130 to put the snap sleeve 110 in a locked state; the two first locking tongue pieces 111 can also be moved away from each other through the locking assembly 130 to put the snap sleeve 110 in an unlocked state.

[0060] Among them, a joint surface 1111 is provided on the inner side of each first locking tongue piece 111, and the joint surface 1111 is constructed to be able to engage with a corresponding mating surface 1211 provided on the buckle plug 120, so that when the buckle sleeve 110 is switched from an unlocked state to a locked state, the buckle plug 120 moves forward along the insertion direction, thereby forming a fixed position that presses the suspension cable 20 into the suspension cable fixing cavity A.

[0061] In this way, when the suspension cable fixing device 10 is used, on the one hand, the buckle sleeve 110 can be fixed to the bottom side of the photovoltaic component 30 by the locking component 130, and on the other hand, the buckle plug 120 can be inserted into the plug accommodating cavity B through the insertion port C, and then the locking component 130 is used to make the two first locking tongue pieces 111 of the buckle sleeve 110 move toward each other, so that the buckle sleeve 110 is switched from the unlocked state to the locked state, and then the buckle plug 120 can be moved forward along the insertion direction, so as to form a fixed position that presses the suspension cable 20 against the suspension cable fixing cavity A, and the locking component 130 can be used to lock the suspension cable 20. The cable fixing device 10 is firmly connected to the bottom side of the photovoltaic component 30, so that the photovoltaic component 30 can be fixed on the cable 20 using the cable fixing device 10. Compared with the traditional cable fastening mechanism, the cable fixing device 10 of the present application is used to install a corresponding photovoltaic component 30 on the cable 20, so that the cable fixing device 10 can be independently adjusted according to the installation position of the photovoltaic component 30, which increases the installation flexibility and convenience of the cable fixing device 10, simplifies the installation process of the photovoltaic component 30, and facilitates the position adjustment of the photovoltaic component 30.

[0062] Optionally, the suspension cable 20 may be a steel cable.

[0063] In some embodiments, see Figure 2 , and refer to Figure 3 and Figure 4 The inner surface of the cable fixing cavity A is constructed as a first crimping arc surface 1121 matching the shape of the cable 20, and the insertion end of the snap plug 120 is constructed with a second crimping arc surface 1212 matching the shape of the cable 20, and the first crimping arc surface 1121 and the second crimping arc surface 1212 cooperate to form a fixed position.

[0064] Specifically, the snap-on sleeve 110 also includes an arc-shaped snap-on sleeve main body 112, one end of the two first locking tongue pieces 111 is a plug-in end to define an insertion port C, and the other ends of the two first locking tongue pieces 111 are respectively connected to the opposite ends of the snap-on sleeve main body 112 along the arc length direction of the first crimping arc surface 1121, and the first crimping arc surface 1121 is arranged on the inner wall of the snap-on sleeve main body 112.

[0065] In this way, when the snap sleeve 110 switches from the unlocked state to the locked state, the snap plug 120 can move forward along the insertion direction, and the suspension cable 20 can be pressed between the first crimping arc surface 1121 and the second crimping arc surface 1212, so that the photovoltaic component 30 can be better fixed on the suspension cable 20 by using the suspension cable fixing device 10.

[0066] In some embodiments, a plurality of crimping bosses 1213 are disposed on both the first crimping arc surface 1121 and the second crimping arc surface 1212 .

[0067] Optionally, the plurality of crimping bosses 1213 on the first crimping arc surface 1121 are arranged at intervals along the arc length direction of the first crimping arc surface 1121 , and the plurality of crimping bosses 1213 on the second crimping arc surface 1212 are arranged at intervals along the arc length direction of the second crimping arc surface 1212 .

[0068] In this way, the multiple crimping bosses 1213 on the first crimping arc surface 1121 and the multiple crimping bosses 1213 on the second crimping arc surface 1212 can be well utilized to limit and fix the suspension cable 20 between the first crimping arc surface 1121 and the second crimping arc surface 1212, so that the suspension cable 20 can be better limited and fixed in the fixed position, and the suspension cable 20 can be more secure after being tightened, and the suspension cable 20 is not easy to rotate in the crimping bosses 1213.

[0069] In this embodiment, the crimping boss 1213 is configured to extend longitudinally, and the insertion direction of the snap plug 120 into the plug accommodating cavity B is perpendicular to the extension direction of the crimping boss 1213 .

[0070] Specifically, the extension direction of the crimping boss 1213 is parallel to the longitudinal extension direction of the cable 20 .

[0071] In this way, the plurality of crimping bosses 1213 on the first crimping arc surface 1121 and the plurality of crimping bosses 1213 on the second crimping arc surface 1212 can be well utilized to make the suspension cable 20 more secure after being compressed, and the suspension cable 20 is not easy to rotate in the crimping bosses 1213 .

[0072] In some embodiments, two engaging surfaces 1111 which are inclined at an angle to the insertion direction of the snap plug 120 and are flared are provided on the inner side of the two first locking tongue pieces 111. The snap plug 120 includes an insertion head 121, a trunk 122 and a tail 123 which are connected in sequence. The insertion head 121 is constructed with a mating surface 1211 which engages with the corresponding engaging surface 1111.

[0073] Since the two engaging surfaces 1111 are arranged at an angle to the insertion direction of the buckle plug 120 and are in a flared shape, and the two first locking tongue pieces 111 are elastic, the buckle plug 120 can be inserted into the plug accommodating cavity B through the insertion port C, and the insertion head 121 is squeezed between the two flared engaging surfaces 1111, so that the matching surface 1211 of the insertion head 121 is abutted against the engaging surface 1111, thereby limiting the outward movement of the buckle plug 120 along the insertion direction of the buckle plug 120, improving the matching reliability between the buckle sleeve 110 and the buckle plug 120, and also facilitating more stably pressing the suspension cable 20 in a fixed position, thereby improving the installation firmness and reliability of the suspension cable fixing device 10.

[0074] In this embodiment, the second crimping arc surface 1212 is disposed on a side of the insertion head portion 121 away from the tail portion 123 and between the two mating surfaces 1211 . A plurality of crimping bosses 1213 are protrudingly disposed on the second crimping arc surface 1212 .

[0075] In some embodiments, the first locking tongue piece 111 is provided with a stopper 1112 at the plugging end of the buckle sleeve 110 , and the tail 123 of the buckle plug 120 is provided with a limiting portion 1231 that can cooperate with the corresponding stopper 1112 to limit the forward movement of the buckle plug 120 along the insertion direction.

[0076] In this way, the matching surface 1211 and the engaging surface 1111 can be used to limit the buckle plug 120 from withdrawing outward along the insertion direction, and the stop portion 1112 and the limiting portion 1231 can be used to limit the forward movement of the buckle plug 120 along the insertion direction. The buckle plug 120 can be well moved forward along the insertion direction to a preset position, thereby forming a fixed position that presses the suspension cable 20 against the suspension cable fixing cavity A.

[0077] In some embodiments, the stop portion 1112 is configured as a stop groove formed at the plug-in end of the first locking tongue piece 111 , and the two limiting portions 1231 are configured as locking edges protruding outward in opposite directions.

[0078] In this embodiment, the notch of the stop groove is arranged around the insertion opening C, and the two limiting portions 1231 are arranged opposite to the bottom wall of the stop groove to limit the forward movement of the buckle plug 120 along the insertion direction.

[0079] In this way, the two limiting portions 1231 can be limited in the stop groove, which can better limit the forward movement of the buckle plug 120 along the insertion direction.

[0080] In some embodiments, the snap-in plug 120 is configured with a groove D extending from the tail portion 123 to the insertion head portion 121 , so that the snap-in plug 120 is configured to form two second locking tongue pieces having elasticity.

[0081] In this way, the insertion head 121 of the snap plug 120 can be more easily squeezed into between the two flared joint surfaces 1111, so that the mating surface 1211 of the insertion head 121 abuts against the joint surface 1111, thereby limiting the outward movement of the snap plug 120 along the insertion direction of the snap plug 120, and thereby pressing the suspension cable 20 into a fixed position.

[0082] In some embodiments, the locking assembly 130 includes a locking member 131 penetrating the first locking tongue piece 111 and the buckle plug 120, and an adjusting member 132 detachably connected to the locking member 131. The adjusting member 132 is configured to be able to be maintained at different positions along the longitudinal extension direction of the locking member 131, so that the two first locking tongue pieces 111 can move toward or away from each other.

[0083] In this way, the adjustment member 132 can be used to adjust the tightness of the connection between the two first locking tongue pieces 111, for example, to make the connection between the two first locking tongue pieces 111 tighter, so that the first locking tongue pieces 111 can move toward each other and the buckle sleeve 110 is in a locked state, or to make the connection between the two first locking tongue pieces 111 looser, so that the first locking tongue pieces 111 can move away from each other and the buckle sleeve 110 is in an unlocked state. In this way, the adjustment member 132 can be used to conveniently switch the buckle sleeve 110 between the locked state and the unlocked state.

[0084] In this embodiment, the adjusting member 132 is threadedly connected to the locking member 131 .

[0085] Specifically, the locking member 131 is a bolt, and the adjusting member 132 is a fastening nut.

[0086] Thus, the first locking tongue pieces 111 can be moved toward each other by tightening the adjusting member 132 to lock the buckle sleeve 110, or the first locking tongue pieces 111 can be moved away from each other by loosening the adjusting member 132 to unlock the buckle sleeve 110.

[0087] According to a second aspect of the present application, a flexible photovoltaic support is provided, comprising a suspension cable 20 , a suspension cable fixing device 10 according to any one of the above embodiments, and a support frame for supporting the suspension cable 20 .

[0088] The suspension cable 20 can be suspended on the ground by using a support frame, so that the photovoltaic components 30 on the suspension cable 20 can be located at a preset height relative to the ground and arranged upward, thereby making good use of the photovoltaic components 30 for photovoltaic power generation.

[0089] According to a third aspect of the present application, a photovoltaic system is provided, including the above-mentioned flexible photovoltaic bracket and a photovoltaic assembly 30 , wherein the photovoltaic assembly 30 includes a frame 31 , and the snap sleeve 110 is connected to the bottom side of the frame 31 through a locking assembly 130 .

[0090] Optionally, see Figure 1 , and refer to Figure 5 The frame 31 includes a bottom wall 311 and a side wall 312 connected vertically. The bottom wall 311 is provided with a through hole. The threaded section 1311 of the locking member 131 passes through the through hole, passes through the two first locking tongue pieces 111 and the buckle plug 120, and is threadedly connected to the adjusting member 132. The end portion 1312 of the locking member 131 abuts against the bottom wall 311.

[0091] In this way, when the photovoltaic system is in use, the snap sleeve 110 can be set on the bottom side of the photovoltaic component 30 through the locking component 130, and the snap sleeve 110 can be switched from the unlocked state to the locked state through the locking component 130. On the one hand, the snap sleeve 110 can be fixed to the bottom side of the photovoltaic component 30, and on the other hand, the snap plug 120 can be moved forward along the insertion direction, thereby forming a fixed position that presses the cable 20 against the cable fixing cavity A. In this way, the cable fixing device 10 can be well utilized to fix the photovoltaic component 30 on the cable 20, and compared with the traditional cable fastening mechanism, the cable fixing device 10 of the present application is used to install a corresponding photovoltaic component 30 on the cable 20, and then the cable fixing device 10 can be independently adjusted according to the installation position of the photovoltaic component 30, which increases the installation flexibility and convenience of the cable fixing device 10, simplifies the installation process of the photovoltaic component 30, and facilitates the position adjustment of the photovoltaic component 30.

[0092] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0093] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
